China's decades-long strategy of absorbing and replicating Western scientific advances is losing steam, and leading scholars warn that entrenched institutional barriers — not just external pressure — now pose the greatest threat to the country's ambition to become a global leader in original innovation. The warning emerged from a high-level dialogue held at the Shanghai Academy of Natural Sciences (SANS) last month, where top researchers convened alongside Kevin Kelly, the founding executive editor of Wired magazine.

The end of replication as a growth engine

Lu Bai, a neurobiologist and the president of SANS, said the catch-up model that powered China's rapid scientific rise across multiple fields is now facing structural limits. 'The path is narrowing for two reasons: first, resistance from the external environment is growing; second, China has reached a stage where there's not much left to simply replicate,' Lu said, according to a transcript of the dialogue published on July 27 by The Intellectual, a social media account he co-founded.

The dual squeeze — tightening access to frontier Western research and a diminishing pool of technologies left to absorb — marks a structural inflection point for Chinese science and technology policy.

Why it matters: institutional culture under scrutiny

Scholars at the SANS symposium identified two core systemic failures holding back original research: a rigid institutional framework that rewards measurable metrics over creative risk-taking, and a deeply ingrained cultural deference to authority. Lu Bai noted these factors were widely recognised among researchers as the primary drag on scientific momentum.

The critique points to a broader tension in China's research ecosystem, where publish-or-perish pressures and top-down hierarchies can suppress the kind of heterodox thinking that drives breakthrough science.

The competitive backdrop: SANS and Shanghai's research push

Established in 2024, SANS is an independent, non-profit institute designed to offer scientists stable, long-term support — a deliberate counterweight to short-term grant cycles. Supervised by the Shanghai government, it forms part of the city's broader pilot zone for basic research, signalling official acknowledgment that the existing model needs reform.

The institute's creation reflects growing recognition at the municipal level that frontier science requires a different institutional logic than applied technology development.

What's next: the innovation imperative

With geopolitical friction limiting access to Western chips, tools, and research networks, the pressure on China to generate homegrown scientific breakthroughs has never been higher. The scholars' candid assessment — delivered inside a state-supervised institution — suggests the conversation about systemic reform is moving from think-tank papers into official forums.

Whether policy can translate that awareness into structural change in research incentives will determine how quickly China can shift from fast-follower to frontier innovator — a transition that will have consequences for the global technology landscape for decades to come.
